I now have 2 Briggs and Riley pieces and I love them. You can't beat the guarantee and the expandable 21" is very cool. It has 2 little buttons that you press and then the bag expands about 3 inches . It's hard to describe. I had to see it to understand but frankly, it gives the bag an " erection" of sorts that makes it deeper.
In any event, I vote B&R - they are way cheaper than Tumi !
